on the obama side, you have two white house veterans who are running the debate prep for president obama. you have senator john kerry, who has been there himself. >> what happens during these mock debates? >> they do not talk a lot about what happens during these. what they try to do is try to set a situation that is as realistic as possible for the actual debate. they do it at the same time and night the debate will take place. they set up a set just like it will look like in denver. they are used the environment. they have somebody to play the moderator and ask questions. obama does not like sound bites. as his campaign will tell you. they force him to give answers. they do whatever they can to simulate the debate situation. >> you quote a former chief of staff to vice-presidents al gore and joe biden. let me read some of his points -- can you elaborate? >> sure. he is not really specifically using this advice for romney or obama, although i have no doubt many of these tips are being passed on to president obama. it is interesting. that was my first short summary of what he has to say.
